IMPROVEMENT m PADDING-MIACHINES.

Specification forming part of Letters Patent No. 184.640, datedNovember'21, 1876; application filed September 7,1876.

To all whom it may concern:

Be it known that EZRA MARBLE, of Lawrence, in the county of Essex andState of Massachusetts, have invented an Improved Padding-Machine, ofwhich the following is a specification This invention relates to apadding-machine for immersing or dyeing textile fabrics; and theinvention consists in the combination, with the color-box andimmersing-roller, of a roller having an impervious seamlessjacket, allsubstantially as hereafter described.

1n the padding of textile fabrics, as heretofore practiced, the rollerabove the immersing-roller has been composed of an iron roll coveredwith textile fabric wound many times about it. This lapped roll, socalled, takes up considerable 'of the color-mixture, which is usuallyvery expensive, and, being saturated, does not act to squeeze from thefabric being dyed or padded as much color as it would do were the coverof the roller impervious to the color-mixture; and, further, the coverof such lapped roll, being of unequal thickness at the point where theouter end of the textile cover terminates on the surface of the roller,acts to press the color unequally from the textile fabric being dyedorpadded, and such fabric presents upon its face a transverse streak orstripe, corresponding with the location of the end of the roller-cover,thereby defacing, in a measure, the fabric and lessening its value.

Fabrics dyed in a paddingniachine present I substantially a uniformdegree of color on both 1 sides or faces thereof; but the lapping of theroller-cover shows injuriously. That portion of the roller where the lapshows or occurs is made harder or thicker than the other portions, and,in passing over the fabric on the immersing roller, subjects the fabricbeing dyed to more pressure, and removes from it a little more color,than does any other portion.

of the roller. To overcome this difficulty and produce a dyed or paddedfabric not defaced by this lap, the fabric has been padded or dyed on aprinting-machine, the fabric, in such machine,passing betweentheimmersing-roller and the usual under cloth, or grey, placed on anendless blanket carried by rollers, in the usual way.

When padding with the printing-machine much color is wasted, the undercloths have to be washed, and the fabric treated in the machine iscolored more on one surface than upon the other, making it necessary touse such fabric one side out to preserve a uniformity of color.

The object of this invention is the production of a machine for paddingtextile fabrics which, in its operation, will not deface the fabric bysubjecting it to more pressure at one point than at another during therotation of the padding-roller, and which, at the same time, will enablethe material dyed or padded to present substantially auniform color oneach of its faces. 1

v Figure 1 represent a sectional elevation of a padding-machineconstructed according to this invention, the line of section being online a: m, Fig. 2; and Fig. 2 is a front view of the machine. r

The frame a is properly. shaped to support the various parts of themachine. The color-.

box I), in which is placed the coloranixture, receives within it theimmersing-roller 0, its journals 01 being supported in suitable boxes onthe frame. Above this immersing-roller, and with its journals 0supported in boxesf,

is the color-distributing roller 9, having an elastic impervioussurface, the surface, in this instance, being a tubular cover (shown atlb) of vulcanized india-rubber or gutta-percha, or equivalent gum, suchcover being of substantially uniform thickness and hardness, wherebyeach portion of the surface thereof acts in a like manner upon thefabric being dyed as it passes between the immersing and spreadingrollers, and the formation of streaks across The fabric 2 is led fromthe fabric is avoided. a suitable roller, i, under the roller 0, andinto the color-box; then up about the roller 0, and between it and thespreading-roller, wherethe fabric is nipped between the peripheries ofthe two rollers, from selvage to selvage, the color being therebyspread-evenly and uniformly, and the excess of color material is forcedback into the color-box. The fabric passing from between the rollers, inthis my improved machine, has the color evenly distributed on bothfaces. This spreading-roller does not absorb the color, and thereforeuses less color than a fabric covered or lapped roller, and by itsuseless coloring material is retained in the fabric as it leaves the rollthan with a lapped roll. This saving" in color-mixture is a matter ofvery great importance in the manufacture of dyed goods.

This machine maybe run at a greater speed than the ordinary machinesheretofore used for this purpose, enabling more work to be accomplishedin the same time, and the work is far superior.

The immersing-roller may be either a plainsnrf'aced metallic roller, ora roller provided with small depressions to assist in taking up colorfrom the color-box, or it may be made of wood or of india-rnbber.

The color-distribntin g roller is held pressed down by any suitablesystem of levers. As herein sbown,asl1ort lever, i, is connected, by

a. link, 7', with a lever, is, weighted at l. The

levert' also carries an adjusting-screw adapted to bear upon thejournal-box of the roller g.

I do not broadly claim an india-rubber-snrfaced roller, for I am awarethat such rollers are commonly used in a variety of machines, and for avariety of different uses; but

i I do claim-- a In a machine for padding, the combination,

with a color-box and immersingroller, of a roller having an imperviousseamless jacket,

all substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
